Saturday Night Fever?

While I'm on holiday, a series of photographs of the quirky or surprising taken along the route of High Street 2012. To find out more about HS2012, visit Diamond Geezer.

If you think there's something wrong about this photo, I've turned it upside-down. It's not a dancefloor, but the lighting in the Barbican Centre. I'm still on holiday, so the photos will be hanging around the Barbican for the next day or so.
